Research overview: morphology versus molecular methods in felid taxonomy

The history of cat classification is largely a story of tension and eventual integration between morphological and molecular approaches. This overview compares the two: morphology, including skull morphometrics, dental characters, and pelage, offers characters applicable to fossils and museum specimens but is vulnerable to convergence, plasticity, and clinal variation; molecular data, from single genes to whole genomes, provide many independent characters and direct estimates of ancestry but can be misled by introgression and incomplete lineage sorting. It discusses landmark cases where the methods conflicted, such as the placement of the snow leopard or the African golden cat, and where they agreed, as in the clouded leopard split. The piece argues that modern felid taxonomy relies on integrating both, with molecular data resolving relationships and morphology providing diagnostic and historical context.
